The Ashes cricket series between England and Australia is traditionally played every two years, with the host country alternating between England and Australia for each edition. However, the actual interval between series can vary from 18 to 30 months, depending on the cricket calendar and the respective seasons in both countries. Each Ashes series consists of five Test matches and is considered one of the sport's most intense and historic rivalries.

In summary:

• The Ashes is played roughly every two years.
• Hosting alternates between England and Australia.
• The exact gap varies (about 18–30 months), mostly due to scheduling requirements.

• Each series comprises five Test matches, continuing a tradition established since the late 19th century.

The next Ashes series is scheduled to be held in Australia from November 2025 to January 2026.
